Description

Methods, apparatus, systems, and storage media for controlling shutter-based stereoscopic display glasses

[0001] This application claims priority to Chinese Patent Application No. 202510247450.9, filed on February 28, 2025, entitled “Method, Apparatus, System and Storage Medium for Controlling Shutter Stereoscopic Display Glasses”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the fields of communication and display, and in particular to a method, apparatus, system and storage medium for controlling shutter stereoscopic display glasses. Background Technology

[0003] Stereoscopic displays can make images appear three-dimensional and realistic, no longer confined to the plane of the screen, but seemingly able to step out of the screen, giving viewers an immersive experience. To achieve stereoscopic displays, shutter-based stereoscopic glasses were invented, which can achieve a stereoscopic effect by increasing the image refresh rate.

[0004] In related technologies, shutter-based stereoscopic display glasses include two lenses: a left lens and a right lens. The display device can display video images, and the user wears the shutter-based stereoscopic display glasses and looks at the video images displayed on the device. The shutter-based stereoscopic display glasses can calculate control information, including a first time period when each lens is in a light-transmitting state and a second time period when it is in a light-blocking state. The shutter-based stereoscopic display glasses control each lens to be in a light-transmitting state during the first time period and to be in a light-blocking state during the second time period, so that the light displayed on the device enters the user's left and right eyes at different times, creating a stereoscopic image in the user's brain, thus achieving stereoscopic display.

[0005] In related technologies, since shutter-based stereoscopic display glasses need to calculate control information, they need to be equipped with high-performance chips and large-capacity batteries to meet the power consumption required for chip calculation. This not only increases the cost of shutter-based stereoscopic display glasses, but also increases their size, weight and power consumption. Summary of the Invention

[0006] This application provides a method, apparatus, system, and storage medium for controlling shutter-based stereoscopic display glasses, thereby reducing the power consumption, size, weight, and cost of shutter-based stereoscopic display glasses. The technical solution is as follows:

[0007] In a first aspect, this application provides a method for controlling shutter-based stereoscopic display glasses. The method is applied to a control device of a communication system. The communication system further includes a display device and shutter-based stereoscopic display glasses. The display device plays a first video, which includes multiple sets of video images. Each set of video images includes a left-eye video image and a right-eye video image, which are two adjacent frames. The lenses of the shutter-based stereoscopic display glasses include multiple regions. In the method, device information of the display device is acquired. Control information is acquired based on the device information, and the control information is used to indicate the state switching time of each region. Control information is sent to the shutter-based stereoscopic display glasses, and the control information is used to instruct the shutter-based stereoscopic display glasses to control each region to be in a light-transmitting state or a light-blocking state at the state switching time of each region.

[0008] Because the control device acquires and sends control information to the shutter-based stereoscopic display glasses, the glasses do not require high computing power to calculate this information. Therefore, there is no need to configure high-performance chips on the glasses, reducing power consumption. This allows for a reduction in battery capacity, which in turn reduces the size and weight of the battery. Consequently, the cost, size, weight, and power consumption of the shutter-based stereoscopic display glasses are all effectively reduced.

[0009] In one possible implementation, the first video is a video obtained by processing the second video to be displayed based on a preprocessing scheme. The display effect of the first video is different from that of the second video. The preprocessing scheme is generated based on device information. Control information is obtained based on the preprocessing scheme and device information.

[0010] The preprocessing scheme is generated based on the device information, and the control information is also obtained based on the device information. Therefore, the preprocessing scheme and the control information acquisition scheme are used together. The preprocessing scheme is used to reduce crosstalk. The first video is obtained by processing the second video to be displayed through the preprocessing scheme. This can effectively reduce crosstalk and improve the stereoscopic display effect.

[0011] In another possible implementation, the position information of the shutter-based stereoscopic display glasses is received. Control information is then acquired based on the position information and device information. This improves the accuracy of the acquired control information.

[0012] In another possible implementation, a frame synchronization signal is sent to the shutter-based stereoscopic display glasses. This frame synchronization signal is derived from the frame header information of the first video and is used to control the shutter-based stereoscopic display glasses to synchronize their clock with the display device. The control information instructs the shutter-based stereoscopic display glasses, after clock synchronization with the display device, to control each area to be in a light-transmitting or light-blocking state at each area's state transition time. In this way, because the shutter-based stereoscopic display glasses control each area to be in a light-transmitting or light-blocking state at each area's state transition time after clock synchronization with the display device, crosstalk can be effectively avoided, improving the stereoscopic display effect.

[0013] In another possible implementation, the device information includes one or more of the following: the display frame rate, scanning method, display panel type, gamma value, response time length, or display delay duration of the display device.

[0014] In another possible implementation, the device information includes the response time and / or display delay of the display device, which is also used to play an initialization video. The system receives the response time and / or display delay of the display device from the shutter-based stereoscopic glasses. This response time and / or display delay is obtained by the shutter-based stereoscopic glasses detecting changes in light and / or image conditions on the display device while playing the initialization video. This allows the system to obtain the response time or display delay of the display device, and control information can be acquired based on this response time or display delay. This control information can avoid crosstalk problems caused by the optical response time of the display device.

[0015] In another possible implementation, the lens includes a left lens and a right lens, and the multiple regions include multiple left-eye regions located on the left lens and multiple right-eye regions located on the right lens. The multiple left-eye regions and the multiple right-eye regions correspond to each other, and the state switching time of each left-eye region is different from the state switching time of the corresponding right-eye region.

[0016] In another possible implementation, a first light-blocking area separates two adjacent left eye regions, and a second light-blocking area separates two adjacent right eye regions.

[0017] In another possible implementation, for each left eye region, the state transition time when the left eye region changes from a light-blocking state to a light-transmitting state is the first moment, the state transition time when the left eye region changes from a light-transmitting state to a light-blocking state is the second moment, the state transition time when the corresponding right eye region changes from a light-blocking state to a light-transmitting state is the third moment, and the state transition time when the corresponding right eye region changes from a light-transmitting state to a light-blocking state is the fourth moment.

[0018] The time difference between the first and second moments, the time difference between the third and fourth moments, the time difference between the first and third moments, and the time difference between the second and fourth moments are all equal to the display duration of one frame of the first video; or,

[0019] The time difference between the first and second moments, and the time difference between the third and fourth moments, are all less than the display duration of one frame of the first video image; the time difference between the first and third moments, and the time difference between the second and fourth moments, are all equal to the display duration of one frame of the first video image; or,

[0020] The time difference between the first and second moments, the time difference between the third and fourth moments, the time difference between the first and third moments, and the time difference between the second and fourth moments are all less than the display duration of one frame of the first video.

[0021] In another possible implementation, the communication system is a fiber-to-the-room (FTTR) system.

[0022] In another possible implementation, the control device is either the master access point or the slave access point of the FTTR system.

[0023] In another possible implementation, the communication technology used between the control device and the shutter-based stereoscopic display glasses is either star-flash communication, Bluetooth communication, infrared communication, or WiFi communication. Therefore, one or more communication technologies can be used between the control device and the shutter-based stereoscopic display glasses, allowing the control device to be adapted to different shutter-based stereoscopic display glasses and improving communication flexibility.

[0024] Secondly, this application provides a device for controlling shutter stereoscopic display glasses. The device is located in a communication system, which further includes a display device and shutter stereoscopic display glasses. The display device is used to play a first video, which includes multiple sets of video images. Each set of video images includes a left-eye video image and a right-eye video image, which are two adjacent frames. The lenses of the shutter stereoscopic display glasses include multiple regions. The device includes:

[0025] The processing unit is used to acquire device information of the display device;

[0026] The processing unit is also used to obtain control information based on the device information, and the control information is used to indicate the state switching time of each area;

[0027] The communication unit is used to send control information to the shutter stereoscopic display glasses. The control information is used to instruct the shutter stereoscopic display glasses to control each area to be in a light-transmitting state or a light-blocking state at the state switching time of each area.

[0028] Since the processing unit acquires control information and the communication unit sends it to the shutter-based stereoscopic display glasses, the glasses do not require high computing power to calculate this information. Therefore, there is no need to configure a high-performance chip on the glasses, reducing power consumption. This allows for a reduction in battery capacity, which in turn reduces the size and weight of the battery. Consequently, the cost, size, weight, and power consumption of the shutter-based stereoscopic display glasses are effectively reduced.

[0029] In one possible implementation, the first video is a video obtained by processing the second video to be displayed based on a preprocessing scheme. The display effect of the first video is different from that of the second video. The preprocessing scheme is generated based on device information. The processing unit is used to obtain control information based on the preprocessing scheme and device information.

[0030] The preprocessing scheme is used to reduce crosstalk. The first video is obtained by processing the second video to be displayed through the preprocessing scheme, which can effectively reduce crosstalk and improve the stereoscopic display effect.

[0031] In another possible implementation, the communication unit is also used to receive position information of the shutter stereoscopic display glasses;

[0032] The processing unit is used to acquire control information based on location and device information. This improves the accuracy of the acquired control information.

[0033] In another possible implementation, the communication unit is also used to send a frame synchronization signal to the shutter stereoscopic display glasses. The frame synchronization signal is obtained based on the frame header information of the first video. The frame synchronization signal is used to control the shutter stereoscopic display glasses to synchronize with the display device. The control information is used to instruct the shutter stereoscopic display glasses to control each area to be in a light-transmitting state or a light-blocking state at the state switching time of each area after synchronizing with the display device.

[0034] In this way, after the shutter-based stereoscopic display glasses are synchronized with the display device, the shutter-based stereoscopic display glasses can control each area to be in a light-transmitting state or a light-blocking state at the time of state switching in each area, which can effectively avoid crosstalk and improve the stereoscopic display effect.

[0035] In another possible implementation, the device information includes one or more of the following: the display frame rate, scanning method, display panel type, gamma value, response time length, or display delay duration of the display device.

[0036] In another possible implementation, the device information includes the response time and / or display delay duration of the display device, which is also used to play an initialization video. A communication unit receives the response time and / or display delay duration of the display device from the shutter stereoscopic display glasses. The response time and / or display delay duration are obtained by the shutter stereoscopic display glasses detecting changes in light and / or image conditions during the playback of the initialization video. Thus, the processing unit can obtain the response time or display delay duration of the display device and acquire control information based on it. This control information can avoid crosstalk problems caused by the optical response time of the display device.

[0037] In another possible implementation, the lens includes a left lens and a right lens, and the multiple regions include multiple left-eye regions located on the left lens and multiple right-eye regions located on the right lens. The multiple left-eye regions and the multiple right-eye regions correspond to each other, and the state switching time of each left-eye region is different from the state switching time of the corresponding right-eye region.

[0038] In another possible implementation, a first light-blocking area separates two adjacent left eye regions, and a second light-blocking area separates two adjacent right eye regions.

[0039] In another possible implementation, for each left eye region, the state transition time when the left eye region changes from a light-blocking state to a light-transmitting state is the first moment, the state transition time when the left eye region changes from a light-transmitting state to a light-blocking state is the second moment, the state transition time when the corresponding right eye region changes from a light-blocking state to a light-transmitting state is the third moment, and the state transition time when the corresponding right eye region changes from a light-transmitting state to a light-blocking state is the fourth moment.

[0040] The time difference between the first and second moments, the time difference between the third and fourth moments, the time difference between the first and third moments, and the time difference between the second and fourth moments are all equal to the display duration of one frame of the first video; or,

[0041] The time difference between the first and second moments, and the time difference between the third and fourth moments, are all less than the display duration of one frame of the first video image; the time difference between the first and third moments, and the time difference between the second and fourth moments, are all equal to the display duration of one frame of the first video image; or,

[0042] The time difference between the first and second moments, the time difference between the third and fourth moments, the time difference between the first and third moments, and the time difference between the second and fourth moments are all less than the display duration of one frame of the first video.

[0043] In another possible implementation, the communication system is a fiber-to-the-room (FTTR) system.

[0044] In another possible implementation, the device is either the master access point or the slave access point of the FTTR system.

[0045] In another possible implementation, the communication technology used between the device and the shutter stereoscopic display glasses is star flash communication technology, Bluetooth communication technology, infrared communication technology, or WiFi communication technology.

[0046] Thirdly, this application provides a communication system, which includes a control device, a display device, and shutter stereoscopic display glasses, wherein the lenses of the shutter stereoscopic display glasses include multiple areas;

[0047] A display device is used to play a first video, the first video including multiple sets of video images, each set of video images including a left-eye video image and a right-eye video image, the left-eye video image and the right-eye video image being two adjacent frames;

[0048] The control device is used to acquire device information of the display device; acquire control information based on the device information, and the control information is used to indicate the state switching time of each area; and send control information to the shutter stereoscopic display glasses.

[0049] Shutter-based stereoscopic display glasses are used to control each area to be in a light-transmitting or light-blocking state at the moment of state switching based on control information.

[0050] The control device acquires control information and sends it to the shutter-based stereoscopic display glasses. This eliminates the need for the glasses to have high computing power to calculate the control information, thus reducing the need for a high-performance chip and power consumption. This, in turn, allows for a smaller battery capacity, which in turn reduces the size and weight of the battery. Therefore, the cost, size, weight, and power consumption of the shutter-based stereoscopic display glasses are all effectively reduced.

[0051] Fourthly, this application provides a control device, which includes a processor, a memory, and a communication interface. The processor is used to execute program instructions in the memory to implement the method provided in the first aspect or any possible implementation of the first aspect.

[0068] Stereoscopic displays can give users an immersive experience and improve the display effect. To achieve stereoscopic display, a three-dimensional first video can be input to the display device. The first video includes multiple sets of video images, each set of video images including one frame of left-eye video image and one frame of right-eye video image. In three-dimensional display mode, the left-eye video image and the right-eye video image are two adjacent video images.

[0069] The display device can play each frame of the first video. The user can wear shutter-based stereoscopic glasses and look at each frame of the video played on the display device. The shutter-based stereoscopic glasses consist of a left and a right lens, which can be controlled to operate in a light-transmitting or light-blocking state at different times, allowing the light from the display device to enter the user's left and right eyes at different times, thus creating a stereoscopic image in the user's brain and achieving stereoscopic display.

[0070] Optionally, each set of video images includes one frame of left-eye video image and one frame of right-eye video image, wherein the one frame of left-eye video image and the one frame of right-eye video image are obtained by converting the same frame of video image.

[0071] Optionally, the first video is a video captured by a binocular camera or a stereo camera, or the first video is an animation, digital image, or game rendered by 3D modeling. The first video itself includes multiple sets of video images, each set of video images including one frame of left-eye video image and one frame of right-eye video image.

[0072] In related technologies, shutter-based stereoscopic display glasses support the same communication technologies as the display devices. This allows the glasses to communicate with the display devices, limiting their flexibility to this type of display. Furthermore, shutter-based stereoscopic display glasses suffer from high cost, large size, heavy weight, and high power consumption. They also cannot resolve crosstalk issues caused by the optical response time of the display devices. Crosstalk refers to the residual image of the previous video frame that a user can see while the display device is displaying a new frame.

[0073] Referring to Figure 1, in order to solve the above problems, this application provides a shutter stereoscopic display glasses 10, which includes a left lens 101 and a right lens 102.

[0074] The left lens 101 includes multiple left eye regions (as shown in the figure, left eye regions 11, 12, 13, 14, and 15), and the right lens 102 includes multiple right eye regions (as shown in the figure, right eye regions 21, 22, 23, 24, and 25). These multiple left eye regions correspond to these multiple right eye regions.

[0075] Optionally, the plurality of left eye regions correspond one-to-one with the plurality of right eye regions. For example, as shown in Figure 1, left eye region 11 corresponds to right eye region 21, left eye region 12 corresponds to right eye region 22, left eye region 13 corresponds to right eye region 23, left eye region 14 corresponds to right eye region 24, and left eye region 15 corresponds to right eye region 25.

[0076] Referring to Figure 2, for any given video frame, the display device displays each row of pixels in that frame sequentially. Let T represent the display duration required to display one frame. This means that the first row of pixels in the frame is displayed at time 0, the last row at time (TT / N), and the first row of the next frame at time T. N is the total number of rows in a video frame, meaning one frame consists of N rows of pixels, where N is an integer greater than 1.

[0077] For example, as shown in Figure 2, left-eye video image 1, right-eye video image 1, left-eye video image 2, and right-eye video image 2 are four consecutive video frames. The first row of pixels in left-eye video image 1 is displayed at time 0, and the last row of pixels in left-eye video image 1 is displayed at time (TT / N). The first row of pixels in right-eye video image 1 is displayed at time T, and the last row of pixels in right-eye video image 1 is displayed at time (2T-T / N). The first row of pixels in left-eye video image 2 is displayed at time 2T, and the last row of pixels in left-eye video image 2 is displayed at time (3T-T / N). The first row of pixels in right-eye video image 2 is displayed at time 3T, and the last row of pixels in right-eye video image 2 is displayed at time (4T-T / N).

[0078] When a left-eye video image is displayed on the display device, for the first image area included in the displayed left-eye video image, one or more left-eye areas corresponding to the first image area in the left lens of the shutter stereoscopic display glasses can be controlled to be in a light-transmitting state, allowing the light displayed by the display device to pass through these light-transmitting areas and illuminate the user's left eye. When a right-eye video image is displayed on the display device, for the second image area in the displayed right-eye video image, one or more right-eye areas corresponding to the second image area in the right lens of the shutter stereoscopic display glasses can be controlled to be in a light-transmitting state, allowing the light displayed by the display device to pass through these light-transmitting areas and illuminate the user's right eye. This allows the light displayed by the display device to enter the user's left and right eyes at different times, creating a stereoscopic image in the user's brain and achieving stereoscopic display.

[0079] In some embodiments, the shutter-based stereoscopic display glasses 10 can be mechanical shutter-based stereoscopic display glasses or liquid crystal shutter-based stereoscopic display glasses, etc. When the shutter-based stereoscopic display glasses 10 are liquid crystal shutter-based stereoscopic display glasses, both the left and right lenses of the shutter-based stereoscopic display glasses 10 are liquid crystal lenses. For example, both the left and right lenses of the shutter-based stereoscopic display glasses 10 are twisted nematic (TN) liquid crystal cells.

[0080] In some embodiments, each area of ​​the shutter stereoscopic display glasses 10 can be controlled by an independent switch to be in a light-transmitting state or a light-blocking state.

[0081] In some embodiments, the width and / or area of ​​each left-eye region on the left lens may be equal or unequal. When the widths of each left-eye region are unequal, the left-eye region opposite the user's left eyeball is typically narrower. For the left-eye regions located to the sides of this left-eye region, the wider the left-eye region is, the further away it is from the original left-eye region. Similarly, the width and / or area of ​​each right-eye region on the right lens may be equal or unequal. When the widths of each right-eye region are unequal, the right-eye region opposite the user's right eyeball is typically narrower. For the right-eye regions located to the sides of this right-eye region, the wider the right-eye region is, the further away it is from the original right-eye region.

[0082] In some embodiments, for any two adjacent left eye regions in the left lens 101, the two left eye regions are separated by a first light-blocking region 16. And for any two adjacent right eye regions in the right lens 102, the two right eye regions are separated by a second light-blocking region 26.

[0083] In some embodiments, when the shutter stereoscopic display glasses 10 are liquid crystal shutter stereoscopic display glasses, the first light-blocking area 16 and the second light-blocking area 26 may have the following structures.

[0084] In the first structure, the first light-blocking area 16 can be a gap between two adjacent left eye areas, the width of which is greater than 0 micrometers and less than or equal to 30 micrometers; the second light-blocking area 26 can be a gap between two adjacent right eye areas, the width of which is greater than 0 micrometers and less than or equal to 30 micrometers.

[0085] In the second structure, the first light-blocking region 16 can be a first black pixel wall filled in the gap between two adjacent left eye regions, the width of the first black pixel wall being greater than 0 micrometers and less than or equal to 100 micrometers; the second light-blocking region 26 can be a second black pixel wall filled in the gap between two adjacent right eye regions, the width of the second black pixel wall being greater than 0 micrometers and less than or equal to 100 micrometers.

[0086] The first and second black pixel walls can be processed using methods such as nanoimprinting, photolithography, inkjet printing, or screen printing.

[0087] The third structure is as follows: the first light-blocking area 16 can be a first black line applied between two adjacent left eye areas, the width of the first black line being greater than 0 micrometers and less than or equal to 100 micrometers, or the width of the first black line being greater than 0 micrometers and less than or equal to 30 micrometers; the second light-blocking area 26 can be a second black line applied between two adjacent right eye areas, the width of the second black line being greater than 0 micrometers and less than or equal to 100 micrometers, or the width of the second black line being greater than 0 micrometers and less than or equal to 30 micrometers.

[0088] The first light-blocking area 16 and the second light-blocking area 26 have a high light-blocking rate. The high light-blocking rate of the first light-blocking area 16 and the second light-blocking area 26 can reduce light leakage between two adjacent areas (left eye area or right eye area), thereby reducing display crosstalk.

[0089] In some embodiments, for each left eye region included in the left lens 101, the state transition time from a light-blocking state to a light-transmitting state for each left eye region may be the same or different, and / or, the state transition time from a light-transmitting state to a light-blocking state for each left eye region may be the same or different. For each right eye region included in the right lens 102, the state transition time from a light-blocking state to a light-transmitting state for each right eye region may be the same or different, and / or, the state transition time from a light-transmitting state to a light-blocking state for each right eye region may be the same or different.

[0090] In some embodiments, for a one-to-one corresponding left and right eye region, the state transition time of the left eye region from a light-blocking state to a light-transmitting state is different from that of the right eye region. Conversely, the state transition time of the left eye region from a light-transmitting state to a light-blocking state is different from that of the right eye region.

[0091] In some embodiments, the light transmittance of each region of the shutter stereoscopic display glasses 10 in a light-transmitting state is adjustable. The light transmittance of each region may be the same or different.

[0092] To improve communication flexibility, reduce the cost, size, weight, and power consumption of the shutter stereoscopic display glasses, and avoid crosstalk, as shown in Figure 3, this application embodiment also provides a communication system 300, which includes shutter stereoscopic display glasses 10, a control device 20, and a display device 30. The control device 20 can communicate with the shutter stereoscopic display glasses 10 and the display device 30.

[0093] Optionally, the lenses of the shutter stereoscopic display glasses 10 include multiple areas.

[0094] Optionally, the shutter stereoscopic display glasses 10 can be the shutter stereoscopic display glasses shown in Figure 2. The lenses of the shutter stereoscopic display glasses 10 include a left lens 101 and a right lens 102. The lenses of the shutter stereoscopic display glasses 10 include multiple left eye regions located on the left lens 101 and multiple right eye regions located on the right lens 102.

[0095] The control device 20 is used to acquire device information of the display device 30, which includes one or more of the following information: display frame rate, scanning method, display panel type, gamma value, response time length or display delay duration of the display device, etc.

[0096] The control device 20 is also used to generate control information based on the device information of the display device 30. The control information is used to indicate the state switching time of each area of ​​the shutter stereoscopic display glasses 10 and to send the control information to the shutter stereoscopic display glasses 10.

[0097] Display device 30 is used to display a first video, which includes multiple sets of video images, each set of video images including a left-eye video image and a right-eye video image.

[0098] The shutter-based stereoscopic display glasses 10 are used to receive the control information and, based on the control information, control each area to be in a light-transmitting state or a light-blocking state at the state switching time of each area, so that the light displayed by the display device enters the user's left and right eyes at different time periods, so as to generate a stereoscopic image in the user's brain and realize stereoscopic display.

[0099] In some embodiments, the control device 20 may also generate a preprocessing scheme based on the device information of the display device, the preprocessing scheme being used to reduce the occurrence of crosstalk.

[0100] In some embodiments, the first video displayed by the display device 30 may be provided by the control device 20. The control device 20 may acquire a second video to be played, the second video comprising multiple sets of video images, each set including one frame of left-eye video image and one frame of right-eye video image. The second video is processed based on a preprocessing scheme to obtain the first video, and the display effect of the first video differs from that of the second video.

[0101] The control device 20 can communicate with the display device 30 via wired or wireless communication. Therefore, the control device 20 can send the processed first video to the display device 30 so that the display device 30 can play the first video.

[0102] In some embodiments, the control device 20 may include a variety of communication technologies. The communication technologies used by the control device 20 to communicate with the shutter stereoscopic display glasses 10 may be the same as or different from the communication technologies used by the control device 20 to communicate with the display device 30, thereby improving communication flexibility.

[0103] Since the control device 20 generates control information and sends it to the shutter stereoscopic display glasses 10, the shutter stereoscopic display glasses 10 do not require high computing power to calculate the control information. Therefore, there is no need to configure a high-computing-power chip on the shutter stereoscopic display glasses 10, reducing its power consumption. This allows for a reduction in the battery capacity of the shutter stereoscopic display glasses 10, which in turn reduces the size and weight of the battery. Therefore, the cost, size, weight, and power consumption of the shutter stereoscopic display glasses 10 are all reduced.

[0104] In some embodiments, the display panel type of the display device 30 can be liquid crystal, light-emitting diode (LED), or organic light-emitting diode (OLED), etc. When the display panel type of the display device 30 is liquid crystal, the device information of the display device 30 acquired by the control device 20 may include the response time length of the display device 30, which is the time required for any pixel in the display device 30 to flip the liquid crystal. The control information generated by the control device 20 is based on the response time length of the display device, and the shutter stereoscopic display glasses 10 control each area to be in a light-transmitting state or a light-blocking state based on the control information, thereby solving the crosstalk problem caused by the optical response time of the display device 30.

[0105] In some embodiments, the shutter stereoscopic display glasses 10 (liquid crystal shutter stereoscopic display glasses) include a main control chip and a battery (not shown in the figure). The main control chip has Wi-Fi communication technology, infrared communication technology, Bluetooth communication technology and / or star flash communication technology, etc., and can communicate with the control device 20 through these communication technologies. The main control chip is powered by a battery, which may be rechargeable or non-rechargeable.

[0106] In some embodiments, the shutter stereoscopic display glasses 10 further includes a measurement unit (not shown in the figure), which is used to measure the first position information and / or delay parameters of the shutter stereoscopic display glasses 10, including the response time length of the display device and / or the display delay duration, etc., and then the shutter stereoscopic display glasses 10 sends the first position information and / or the delay parameters to the control device 20.

[0107] In some embodiments, the shutter stereoscopic display glasses 10 may include a detector and / or a signal feedback device, etc. The detector may include a light intensity detector and / or an image sensor, etc. The detector can be used to detect the time delay parameter, and the time delay parameter can be sent to the control device 20 through the signal feedback device.

[0108] Optionally, the shutter-based stereoscopic display glasses 10 may also include a computing unit and / or a storage unit, etc., and / or a photodetector optical module, which is used to initialize and calibrate the response time and / or display delay of the display device, etc.

[0109] The control device 20 is used to receive the first position information and generate the control information based on the first position information and the device information of the display device 30.

[0110] In some embodiments, the first position information of the shutter stereoscopic display glasses 10 can be an absolute position or a relative position, etc. Optionally, the absolute position can be the position of the shutter stereoscopic display glasses 10 in a three-dimensional coordinate system, and the relative position can include the relative distance between the shutter stereoscopic display glasses 10 and the display device 30, and / or the relative height between the shutter stereoscopic display glasses 10 and the display device 30, etc.

[0111] Optionally, the first position information of the shutter stereoscopic display glasses 10 can be obtained by means of ultra-wideband positioning, Bluetooth low-power positioning, WiFi positioning, radio frequency identification positioning, ultrasonic positioning, inertial measurement unit, lidar, and / or visual / visible light positioning.

[0112] Optionally, the main control chip of the shutter stereoscopic display glasses 10 may also include the power supply circuit and control circuit of the liquid crystal shutter.

[0113] In some embodiments, referring to FIG4, the control device 20 includes one or more of the following modules: network module 201, video conversion module 202, video preprocessing module 203, measurement and initialization module 204, and synchronization control module 205, etc.

[0114] Network module 201 is used to acquire a second or third video to be played. The third video may be a two-dimensional video or a three-dimensional ordinary video.

[0115] The second video includes multiple sets of video images, each set of video images including one frame of left-eye video image and one frame of right-eye video image.

[0116] The third video is a three-dimensional ordinary video. The third video consists of multiple consecutive frames of video images. The video images of two adjacent frames are video images that were captured or generated at different times. The third video does not contain left-eye video images and right-eye video images.

[0117] When the network module 201 acquires the third video, the video conversion module 202 is used to convert the two-dimensional third video into a three-dimensional third video if the third video is two-dimensional. The conversion is performed on each frame of the three-dimensional third video to obtain a second video. The second video includes a set of video images corresponding to each frame of the three-dimensional third video, including left-eye and right-eye video images. If the third video is a three-dimensional ordinary video, the conversion is performed on each frame of the three-dimensional third video to obtain the second video. The second video includes a set of video images corresponding to each frame of the three-dimensional third video, including left-eye and right-eye video images.

[0118] The video preprocessing module 203 is used to process the second video based on the preprocessing scheme to obtain the first video. The display effect of the second video is different from that of the first video. The first video is input to the display device 30.

[0119] The measurement and initialization module 204 is used to obtain device information of the display device 30 from the display device 30. The device information obtained from the display device 30 includes one or more of the following information: display frame rate, scanning method, display panel type and / or gamma value of the display device 30, etc.

[0120] The measurement and initialization module 204 is used to obtain the response time length and / or display delay duration of the display device using the shutter stereoscopic display glasses 10, and to receive the first position information of the shutter stereoscopic display glasses 10.

[0121] The synchronization control module 205 is used to generate control information based on the device information of the display device 30 and send the control information to the shutter stereoscopic display glasses 10.

[0122] In some embodiments, the synchronization control module 205 can also generate control information based on the preprocessing scheme and the device information of the display device 30. Both the preprocessing scheme and the control information are derived from the device information, so the resulting preprocessing scheme and the scheme for obtaining the control information are complementary. The preprocessing scheme is used to reduce crosstalk, for example, to reduce crosstalk caused by the optical response time of the display device 30. Therefore, by processing the second video using the preprocessing scheme to obtain the first video, and generating control information based on the preprocessing scheme and the device information of the display device 30, crosstalk can be effectively reduced, improving the stereoscopic display effect.

[0123] In some embodiments, the control device 20 may also include an encoding / decoding module 206.

[0124] When the network module 201 obtains the third video, the encoding / decoding module 206 decodes the third video, inputs the decoded third video into the video conversion module 202, and then the video conversion module 202 converts the decoded third video to obtain the second video.

[0125] When the network module 201 obtains the second video, the encoding / decoding module 206 decodes the second video and inputs the decoded second video into the video preprocessing module 203. Then, the video preprocessing module 203 processes the decoded third video to obtain the first video.

[0126] In some embodiments, the display device 30 may be a television, a desktop monitor, or a mobile smart screen, etc. The control device 20 may transmit or project the processed first video onto the display device 30 via wired communication using a high definition multimedia interface / displayport (HDMI / DP) or wireless communication using WiFi or millimeter wave, and the display device 30 may then play the first video.

[0127] In some embodiments, the communication system 300 described above can be a Fiber To The Room (FTTR) system, and the control device 20 can be a separate device in the FTTR system. Alternatively, the control device 20 can be integrated with the master or slave access point in the FTTR system, that is, the control device 20 can be the master or slave access point in the FTTR system.

[0128] Optionally, the main access point can be a main gateway, and the secondary access point can be a secondary gateway. For example, the main access point can be a master fiber unit (MFU), and the secondary access point can be a sub-fiber unit (SFU). The FTTR system can support gigabit-capable passive optical network (GPON), 10GPON, or 50GPON network communication, has WiFi 6 or higher WiFi communication modules, supports star-flash communication technology, infrared communication technology, and / or Bluetooth communication technology, has multiple high-speed network interfaces, supports intelligent network management functions, and can be controlled and managed through corresponding applications.

[0129] Referring to Figure 5, this application embodiment provides a method 500 for controlling shutter stereoscopic display glasses. The method 500 is applied to the communication system 300 shown in Figure 3 or Figure 4. The method 500 includes the following process.

[0130] Step 501: Control device obtains device information of display device.

[0131] The device information of a display device includes one or more of the following: display frame rate, scanning method, display panel type, gamma value, response time length, or display latency duration.

[0132] In some embodiments, the extended display identification data (EDID) of a display device includes one or more of the following information: display frame rate, scanning method, display panel type, or gamma value of the display device.

[0133] The control device can establish a connection with the display device using wired or wireless communication. Through this connection, it can read information such as the display frame rate, scanning method, display panel type, and / or gamma value from the display device's EDID.

[0134] In some embodiments, the control device may include an initialization video, which is input to a display device to cause the display device to play the initialization video. The shutter stereoscopic display glasses detect changes in light emitted by the display device and / or changes in the displayed image while the initialization video is playing. Based on these changes, the control device obtains the response time and / or display delay of the display device and sends this information to the control device. The control device receives the response time and / or display delay of the display device to obtain device information about the display device.

[0135] In some embodiments, the shutter-based stereoscopic display glasses include a detector through which the display delay duration of the display device can be obtained. Optionally, the detector includes a light intensity detector and / or an image detector, etc.

[0136] Optionally, several examples of obtaining the display delay duration of a display device are listed below. Of course, in addition to the examples described below, other examples can be used to obtain the display delay duration, which will not be listed and explained here.

[0137] Example 1: The initialization video includes a left-eye video image with completely white content and a right-eye video image with completely black content. The left lens of the shutter stereoscopic display glasses includes M left-eye regions, and the right lens includes M right-eye regions, where M is an integer greater than 0. The control device can cyclically input the left-eye and right-eye video images included in the initialization video to the display device, causing the display device to loop through these images. The control device also records the input time of each frame of video image input to the display device.

[0138] The shutter-based stereoscopic display glasses control the i-th left eye region in T. i1 The system switches between light-blocking and light-transmitting states at specific times, i = 1, 2, 3...M, and controls the i-th right eye region in T... i2 The T constantly switches from a light-blocking state to a light-transmitting state. i2 =T i1 +1 / T, where T is the display duration of one frame of the initial video image displayed on the display device. The first left-eye region is the top left-eye region of the left lens, the Mth left-eye region is the bottom left-eye region of the left lens, the first right-eye region is the top right-eye region of the right lens, and the Mth right-eye region is the bottom right-eye region of the right lens.

[0139] Among them, the T region of the i-th left eye area changes from a light-blocking state to a light-transmitting state. i1 At time T, the j-th left eye region switches from a light-blocking state to a light-transmitting state. j1 The time difference between moments is equal to T / M, and j = i + 1. Therefore, the time T for the first left eye region to switch from a light-blocking state to a light-transmitting state is... 11 The time T when the Mth left eye region switches from a light-blocking state to a light-transmitting state. M1 The time difference between the two moments is T.

[0140] The T region of the i-th right eye area changes from a light-blocking state to a light-transmitting state. i2 Time T and the time when the j-th right eye region changes from a light-blocking state to a light-transmitting state j2 The time difference between moments is equal to T / M. Therefore, the time T for the first moment when the right eye region changes from a light-blocking state to a light-transmitting state is... 12 The time T when the Mth right eye region switches from a light-blocking state to a light-transmitting state. M2 The time difference between the moments is T.

[0141] The light from the initial video playback on the display device can pass through the left eye area (which is in a transparent state) on the left lens and the right eye area (which is in a transparent state) on the right lens. The detector of the shutter stereoscopic display glasses can detect the first light intensity transmitted through the left eye area on the left lens and the second light intensity transmitted through the right eye area on the right lens, and also record the detection time of the first light intensity and the detection time of the second light intensity.

[0142] The shutter-based stereoscopic display glasses can acquire the target detection time, and send the first time when the detected light intensity is at its maximum and the second time when the detected light intensity is at its minimum to the control device. The control device receives the target detection time, retrieves the target input time that is before and closest to the target detection time from the recorded input times, and calculates the time difference between the target input time and the target detection time to obtain the display delay duration of the display device.

[0143] The display duration of a single video frame on a display device is based on the device's frame rate. For example, assuming a frame rate of 120Hz, the display duration T for one frame is 1 / 120 = 8.33 milliseconds. Further assuming a frame rate of 60Hz, the display duration T for one frame is 1 / 60 = 16.66 milliseconds.

[0144] Example 2, referring to Figure 6(a), the initial video includes a left-eye video image and a right-eye video image. The left-eye video image includes two parallel first standard lines, a rectangular first background pattern, and a rectangular foreground pattern. The height of the first background pattern is equal to the height of the left-eye video image, and the height of the foreground pattern is equal to the interval between the two first standard lines. The width of the first background pattern is less than the width of the left-eye video image, and the width of the first background pattern is equal to the width of the foreground pattern. The foreground pattern is located between the two first standard lines. The right-eye video image includes two parallel second standard lines and a rectangular second background pattern. The shape and size of the first background pattern are the same as those of the second background pattern. The interval between the two first standard lines is the same as the interval between the two second standard lines, and the positions of the two first standard lines in the left-eye video image are the same as the positions of the two second standard lines in the right-eye video image.

[0145] The control device inputs an initialization video to the display device, causing the display device to loop the initialization video. The user wears shutter-based stereoscopic glasses, closing their right eye and keeping only their left eye open. A control interface for the shutter-based stereoscopic glasses is displayed on a mobile phone or computer. This interface includes a time delay progress bar, which controls the timing of when the left and right lenses of the shutter-based stereoscopic glasses switch from a light-blocking state to a light-transmitting state. The user can drag the progress bar to control the shutter-based stereoscopic glasses to switch the left and right lenses from a light-blocking state to a light-transmitting state at different times. Referring to Figure 6(b), when the user sees the two first standard lines and two second standard lines in the left and right video images aligned, the first foreground image and the second foreground image aligned and stitched together, and the foreground pattern located between the aligned two standard lines, the time delay corresponding to the current progress of the time delay progress bar is obtained. Based on this time delay, the display delay duration of the display device is calculated.

[0146] Optionally, the first background pattern has the same color as the second background pattern, while the foreground pattern has a different color from the first background pattern. For example, both the first and second background patterns are red, and the foreground pattern is green. Or, for another example, both the first and second background patterns are white, and the foreground pattern is black.

[0147] Example 3: The initialization video consists of multiple video frames, and the brightness variation pattern of these frames follows a preset pattern. For example, as shown in Figure 7, the brightness variation pattern of these multiple video frames follows the preset pattern indicated by the waveform shown in Figure 7. The control device can first measure the round-trip time delay between itself and the shutter stereoscopic display glasses. Then, the control device inputs the initialization video to the display device, causing the display device to play the initialization video, and also obtains the input time of the initialization video.

[0148] The detector in the shutter-based stereoscopic display glasses can detect the brightness variation pattern during the playback of the initialization video on the display device. Once the display device has finished playing the complete initialization video, the shutter-based stereoscopic display glasses can detect the complete brightness variation pattern and send the detection time to the control device. This detection time is the moment when the complete brightness variation pattern is detected. The control device receives this detection time and calculates the display delay duration of the display device according to the following first formula.

[0149] The first formula is: Ttv = T - TT - Tpe;

[0150] In the first formula, Ttv is the display delay of the display device, T is the time length between the detection time and the input time, TT is the round-trip delay, and Tpe is the total duration of playing the multi-frame video image.

[0151] In some embodiments, the control device further acquires first position information of the shutter stereoscopic display glasses. Optionally, in implementation: the control device may send a position acquisition command to the shutter stereoscopic display glasses. The shutter stereoscopic display glasses receive the position acquisition command, acquire their own first position information, and send the first position information to the control device. The control device receives the first position information of the shutter stereoscopic display glasses.

[0152] Optionally, the shutter stereoscopic display glasses include a measurement unit for measuring first position information of the shutter stereoscopic display glasses.

[0153] Optionally, the first position information of the shutter stereoscopic display glasses may include the absolute or relative position of the shutter stereoscopic display glasses.

[0154] Optionally, the absolute position can be the position of the shutter stereoscopic display glasses in a three-dimensional coordinate system, and the relative position can include the relative distance between the shutter stereoscopic display glasses and the display device, and / or the relative height between the shutter stereoscopic display glasses and the display device, etc.

[0155] Optionally, the position information of the shutter stereoscopic display glasses can be obtained using ultra-wideband positioning, Bluetooth Low Energy positioning, WiFi positioning, radio frequency identification positioning, ultrasonic positioning, inertial measurement unit, lidar, and / or visual / visible light positioning.

[0156] Step 502: The control device acquires the second video to be played, processes the second video based on the preprocessing scheme to obtain the first video, and the display effect of the first video is different from that of the second video.

[0157] In some embodiments, the preprocessing scheme is determined by the control device based on the device information of the display device, and the preprocessing scheme is used to reduce the occurrence of crosstalk.

[0158] In some embodiments, the display effect of the first video and the display effect of the second video are different, including one or more of the following situations: the color information of the first video and the color information of the second video are different; the brightness information of the first video and the brightness information of the second video are different; or the stereo parallax of the first video and the stereo parallax of the second video are different; or the resolution / clarity of the first video and the resolution / clarity of the second video are different.

[0159] Optionally, the second video may be obtained by converting the received third video. The third video can be a two-dimensional video or a three-dimensional ordinary video. If the third video is a two-dimensional video, the control device needs to convert the two-dimensional third video into a three-dimensional third video after receiving it. The three-dimensional third video includes depth information, and in this case, the three-dimensional third video is a three-dimensional ordinary video.

[0160] Two-dimensional third video includes two-dimensional information, namely horizontal and vertical information, while three-dimensional third video includes three-dimensional information, namely horizontal, vertical and depth information.

[0161] Optionally, the second or third video can be network video, and the control device receives the second or third video. For example, the second or third video might be Internet Protocol Television (IPTV), over-the-top (OTT) service video, streaming video, cloud video, or video from a network storage device. For instance, the network storage device could be network attached storage (NAS), and the video from the network storage device could be video from the NAS.

[0162] Optionally, the second or third video can be video transmitted from a local device. For example, the second or third video could be images, videos, or game content sent from a computer or game console to the control device via wired or wireless communication. Alternatively, the second or third video could be content projected from a local device such as a mobile phone, tablet (PAD), or Internet of Things (IoT) device to the control device via wired or wireless communication.

[0163] In some embodiments, to achieve stereoscopic display, after converting to obtain a three-dimensional third video or receiving a three-dimensional third video, it is necessary to convert each frame of the three-dimensional third video to obtain a second video. The second video includes a set of video images corresponding to each frame of the third video. For each frame of video image, the set of video images corresponding to that frame includes a left-eye video image and a right-eye video image. The left-eye video image and the right-eye video image are obtained by converting that frame of video image. The disparity information of the left-eye video image and the right-eye video image are different. That is, the second video obtained after conversion includes multiple sets of video images, each set of video images including a left-eye video image and a right-eye video image, which are two adjacent video images.

[0164] In some embodiments, the second or third video is an encoded video. Before processing the second or third video, the control device decodes it and then processes the decoded second or third video. For example, the decoded third video is converted to obtain the second video, and / or the decoded second video is processed based on a preprocessing scheme to obtain the first video.

[0165] Step 503: The control device sends the first video to the display device.

[0166] In some embodiments, when the control device and the display device communicate via wired communication, the control device can directly send the first video to the display device. Alternatively, when the control device and the display device communicate via wireless communication, the control device can encode the first video to obtain an encoded first video and then send the encoded first video to the display device.

[0167] In some embodiments, the control device further obtains a frame synchronization signal based on the frame header information of the first video and sends the frame synchronization signal to the shutter stereoscopic display glasses. The shutter stereoscopic display glasses receive the frame synchronization signal and synchronize their clock with the display device based on the frame synchronization signal.

[0168] Optionally, the control device can periodically or irregularly acquire a frame synchronization signal and send the frame synchronization signal to the shutter stereoscopic display glasses. This allows the shutter stereoscopic display glasses to periodically or irregularly synchronize their clock with the display device based on the frame synchronization signal.

[0169] Step 504: The control device obtains control information based on the device information of the display device. The control information is used to indicate the state switching time of each area in the shutter stereoscopic display glasses.

[0170] In some embodiments, for step 504, the control device may obtain control information based on the device information of the display device and the first position information of the shutter stereoscopic display glasses. Alternatively, the control device may obtain control information based on the device information of the display device and a preprocessing scheme.

[0171] In step 504, the control device can acquire second position information of each area of ​​the shutter stereoscopic display glasses on the shutter stereoscopic display glasses. Then, the control device can acquire control information based on the second position information and the device information of the display device. Alternatively,

[0172] The control device can obtain control information based on the second position information, the device information of the display device, and the first position information of the shutter stereoscopic display glasses. Alternatively,

[0173] The control device can obtain control information based on the second location information, the device information of the display device, and the preprocessing scheme. Alternatively,

[0174] The control device can obtain control information based on the second position information, the device information of the display device, the first position information of the shutter stereoscopic display glasses, and the preprocessing scheme.

[0175] Optionally, the control device can obtain the position of each left-eye region of the shutter stereoscopic display glasses on the left lens and the position of each right-eye region on the right lens based on the second position information. Then, it combines this with the information from the display device to derive control information; or, it combines the device information of the display device and the first position information of the shutter stereoscopic display glasses to derive control information; or, it combines the device information of the display device and a preprocessing scheme to derive control information; or, it combines the device information of the display device, the first position information of the shutter stereoscopic display glasses, and a preprocessing scheme to derive control information.

[0176] The control information can be obtained based on the display device's equipment information, and the preprocessing scheme is also based on the display device's equipment information. Therefore, the preprocessing scheme and the scheme for obtaining control information are used in conjunction. The second video is processed using the preprocessing scheme to obtain the first video, which is then played by the display device. The shutter-based stereoscopic display glasses control the state switching time of each area based on the control information, thereby effectively reducing crosstalk.

[0177] Optionally, the control information may include the state transition times for each left eye region (from occlusion to light transmission) and from light transmission to occlusion, and for each right eye region (from occlusion to light transmission and from light transmission to occlusion). Alternatively,

[0178] The control information may include the time when each left eye region switches from a light-blocking state to a light-transmitting state, and the duration of light transmission in each left eye region; similarly, the time when each right eye region switches from a light-blocking state to a light-transmitting state, and the duration of light transmission in each right eye region. Alternatively,

[0179] The control information may include the time when each left eye region switches from a light-transmitting state to a light-blocking state and the duration of light-blocking in each left eye region, as well as the time when each right eye region switches from a light-transmitting state to a light-blocking state and the duration of light-blocking in each right eye region.

[0180] For each region (left eye or right eye region), the time difference between the current state transition from light-transmitting to light-blocking and the next state transition can be equal to the sum of the time it takes to display one frame of left-eye video image and the time it takes to display one frame of right-eye video image, which is equal to 2T. The time it takes to display one frame of left-eye video image and the time it takes to display one frame of right-eye video image are both equal, T. Furthermore,

[0181] The time difference between the current state transition from light-blocking to light-transmitting in this region (left eye region or right eye region) and the next state transition from light-blocking to light-transmitting can be equal to the sum of the time it takes to display one frame of left eye video image and the time it takes to display one frame of right eye video image, which is equal to 2T.

[0182] Step 505: The control device sends control information to the shutter stereoscopic display glasses.

[0183] In step 505, the control device can send control information to the shutter stereoscopic display glasses via wireless communication. Optionally, the communication technology used in this wireless communication method can be star-flash communication technology, Bluetooth communication technology, infrared communication technology, millimeter-wave communication technology, or WiFi communication technology.

[0184] In some embodiments, the control device may periodically or irregularly acquire control information and then send the control information to the shutter stereoscopic display glasses.

[0185] Step 506: The display device receives the first video and plays the first video.

[0186] If the control device and the display device communicate wirelessly, the first video received by the display device is the encoded first video. Therefore, the display device decodes the first video and plays the decoded first video.

[0187] The first video includes multiple sets of video images, each set including one frame of left-eye video image and one frame of right-eye video image. The display device can display each frame of the first video one by one. During display, the display device can first display the left-eye video image from a set of video images, then display the right-eye video image from the same set of video images, then first display the left-eye video image from the next set of video images, and then display the right-eye video image from the next set of video images.

[0188] Step 507: The shutter stereoscopic display glasses receive control information and, based on this control information, control each area to be in a light-transmitting state or a light-blocking state at the state switching time of each area it includes.

[0189] After synchronizing the control device with the display device based on the frame synchronization signal, the control device controls each area to be in a light-transmitting state or a light-blocking state at the state switching time of each area included in the shutter stereoscopic display glasses based on the control information.

[0190] In step 507, the shutter stereoscopic display glasses receive control information. Based on this control information, the switching times of each area from a light-blocking state to a light-transmitting state and vice versa can be obtained. At each switching time from a light-blocking state to a light-transmitting state, the system controls the transition of each area from a light-blocking state to a light-transmitting state, and vice versa.

[0191] For each region, based on the current state transition time from shading to light transmission, the next state transition time from shading to light transmission can be obtained. Similarly, based on the current state transition time from light transmission to shading, the next state transition time from light transmission to shading can be obtained. Thus, at the next state transition time from shading to light transmission, the region is controlled to switch from a shading state to a light transmission state, and vice versa.

[0192] In some embodiments, the state switching time of each left-eye region is different from the state switching time of the corresponding right-eye region. This ensures that the light displayed by the device enters the user's left and right eyes at different times to create a stereoscopic image in the user's brain, thus achieving stereoscopic display.

[0193] In some embodiments, referring to FIG8, when the display device displays a left-eye video image, the first image area already displayed in the left-eye video image corresponds to at least one left-eye area in the left lens of the shutter stereoscopic display glasses. At the state transition moment when the shutter stereoscopic display glasses have switched from a light-blocking state to a light-transmitting state based on the at least one left-eye area, the at least one left-eye area is controlled to switch from a light-blocking state to a light-transmitting state. Light displayed by the display device can pass through the at least one left-eye area and illuminate the user's left eye, allowing the user's left eye to see the displayed first image area.

[0194] When the display device displays a right-eye video image, the second image area already displayed in the right-eye video image corresponds to at least one right-eye area in the right lens of the shutter stereoscopic display glasses. At the moment when the shutter stereoscopic display glasses have switched from a light-blocking state to a light-transmitting state based on the at least one right-eye area, the at least one right-eye area is controlled to switch from a light-blocking state to a light-transmitting state. Light displayed by the display device can then pass through the at least one right-eye area and illuminate the user's right eye, allowing the user's right eye to see the displayed second image area.

[0195] In this way, the user's left and right eyes see the first and second image areas displayed by the display device at different times, thus allowing the user to see the first video of the stereoscopic display.

[0196] In some embodiments, for each left eye region and for the corresponding right eye region, the state transition time when the left eye region switches from a light-blocking state to a light-transmitting state is the first moment, the state transition time when the left eye region switches from a light-transmitting state to a light-blocking state is the second moment, the state transition time when the right eye region switches from a light-blocking state to a light-transmitting state is the third moment, and the state transition time when the right eye region switches from a light-transmitting state to a light-blocking state is the fourth moment.

[0197] Referring to Figure 9, the time difference between the first and second moments, the time difference between the third and fourth moments, the time difference between the first and third moments, and the time difference between the second and fourth moments are all equal to the display duration T of one frame of the first video. Alternatively,

[0198] Referring to Figure 10, the time difference between the first and second moments, and the time difference between the third and fourth moments, are all less than the display duration T of one frame of the first video image. Conversely, the time difference between the first and third moments, and the time difference between the second and fourth moments, are equal to the display duration T of one frame of the first video image. Alternatively,

[0199] Referring to Figure 11, the time difference between the first and second moments, the time difference between the third and fourth moments, the time difference between the first and third moments, and the time difference between the second and fourth moments are all less than the display duration T of one frame of the first video image.

[0200] When the shutter-based stereoscopic display glasses receive control information again, they acquire the state transition time for each area to switch from a light-blocking state to a light-transmitting state, as well as the state transition time for each area to switch from a light-transmitting state to a light-blocking state, based on the next received control information. This improves the accuracy of the shutter-based stereoscopic display glasses in acquiring the state transition times.

[0201] In this embodiment, the control device acquires control information and then sends it to the shutter-based stereoscopic display glasses. This eliminates the need for the stereoscopic display glasses to calculate control information independently, thus reducing the need for a high-performance chip and power consumption. Because of this reduced power consumption, a larger capacity battery is sufficient to further reduce the size and weight of the glasses. Furthermore, the control device acquires control information based on the display device's device information, including its response time and / or display delay. This reference to the display device's optical response time avoids crosstalk issues caused by the optical response time. The control device can incorporate multiple communication technologies. The communication technologies used between the control device and the display device may be the same or different from those used between the control device and the stereoscopic display glasses, allowing the stereoscopic display glasses to be used with different types of display devices and improving flexibility. In addition, since it is possible to measure the response time and / or display latency of the display device, and to obtain information such as the display frame rate, scanning method, display panel type and / or gamma value of the display device, the display device can be of different types or from different manufacturers, or the display device can work in different display modes or image styles. Therefore, it improves flexibility, is compatible with various displays and their multiple display modes, ensures playback effect, and reduces display crosstalk.
